Serial No. 419,288.

T 0 all whom it may concern:

Be it known that I, PETER G. SCHMIDT, a citizen of the United States, and a resident of Tumwater, in the county of Thurston and State of Washington, have invented certain new and useful Improvements in Regulators for Producers, of which the following is a specification.

My invention is an improvement in regulators for producers and consists in certain novel construct-ions and combinations of parts hereinafter described and claimed.

The regulator is especially adapted for use in gas producers, and is designed to automatically regulate the admission of air, water, steam and inert gas to the producer, and to properly proportion the mixture.

Referring to the drawings forming a part hereof Figure 1 is a side view of the improvement partly in section. Fig. 2 is partial plan view of the water cup. Fig. is a section on the line 33 of Fig. 1. Fig. is perspective view of a portion of Fig. 1 and Fig. 5 is a section on the line 5--5 of Fig. 1.

In the present embodiment of my invention, the water cup 1 is connected to a balanced lever 2, by means of bolts or rivets 3, the lever being balanced in the fork 4., of a suitable bracket 5. The water cup 1 is pro-- vided with a spout, having an inclined bottom 6, and parallel side walls 7, and the top and bottom of the spout at the junction of the cup therewith are provided with recesses for receiving the trunnions of a gate 8, mounted to swing between the walls '7 to close the opening between the water cup and the spout. The edges 10 of one side of the gate 8 are beveled in opposite directions, as shown in Fig. 3, and the trunnions of the gate are arranged on the unbeveled side, so that the axis upon which the gate swings is in the plane of such side. This arrangement prevents impurities from choking the gate the beveled edges acting to keep the walls 7 clear at the point where the edges contact therewith.

The bottom of the water cup is provided with a central opening, and a tube 12 ex tends through the opening, the tube being provided with a flange 13 connected by rivets 14L with the container. The upper end of the tube is internally threaded for some distance and is annularly recessed below the threaded portion as at 15, and an over-flow pipe 16 is provided with a threaded pora-com tion 17, for engaging the thread of the tube 12, the drip pipe being provided outside of the cup with a hand wheel 18, whereby to rotate said pipe to raise it and lower it in the water cup. The outer end of the tube 12 is provided with a packing nut 19, between which and the tube is a packing 20.

It will be noticed that the upper end of the drip tube, is at the horizontal center of the water cup, for which reason the opening of the tube will always be at the center of oscillation of the water in whatever position the water cup may be. A funnel 21 is arranged below the drip pipe, into which the drip pipe delivers.

A casing 22 is provided, one end of which communicates with the producer, and the other end is provided with a velve seat 23,

normally closed by a valve 24:, whose stem 25 is pivoted at 26 to one end of the lever 2, the opposite end being provided with a weight 27 adjustable thereon. The valve seat 23 is formed by a flange on the endof the casing, the said flange curved outwardly being provided with a down pipe 33, and an up pipe 31, which leads into an annular depression formed by the flange of the easing as it bends outwardly from the casing.

A pipe 36 leads from one side of the eas- Stops 31 85 ing, the said pipe being provided with a check valve 37 opening toward the casing, and the pipe divides into branches 38, 39, beyond the funnel 21 before mentioned. A valve 40 is pivotally mounted in each of the branches 38, 39, and the stem 41 of each of the valves is encircled by a sleeve 42, provided with a set screw 43, whereby it may be adjusted on the stem. To each sleeve is pivoted the inner member 441 of a telescoping link, the outer member 45 of the link being pivoted to a sleeve 46, adjustable on an. arm 47, of a yoke 48, whose body portion is connected with the lever 2 before described as at 49. It will be evident that when the lever 2 is rocked the yoke 18 will be moved to operate the valves and by means of the adjustable sleeve and the telescoping links,

this movement may be adjusted to secure a very slight movement of the valves, or a considerable movement as may be desired. The valves may be adjusted to open to different extents whereby to admit a greater amount of fluid through one pipe than the other if desired.

To the pipe 38, is connected at suitable source of steam supply, and to the pipe 39 is connected a suitable source of inert gas, such as for instance, the exhaust from a gas engine, and the extent of opening of the valves in the pipes 38,39 may be so adjusted as, to admit a suitable mixture of steam and inert gas to the casing 22 under circum; stances to be presently described. A pipe 50 leads from the casing on the opposite side from the pipe 36, the pipebeing provided with a check valve 51 opening toward the casing 22 and divided beyond the valve into branches 52, 53, the branch 52 being connected to a source of steam supply, and the branch 53 to a source of inert gas. A valve 54 is arranged in the pipe 50, the stem of the valve being rigid with a lever 55, provided at 'one end with an adjustable weight 56, and at the other end with a sleeve 59 adjustable on the lever and secured in place by a set screw 60. The outer member 61 of an extensible link is pivoted to the sleeve 59, and. the inner member 62 is pivoted, to another sleeve 63, adjustable on the lever 64, of a thermostat control, the sleeve being retained in its adjusted position by a set screw 65. A set crew 62* retains the members of the extensible link in their adjustable position. The opposite end of the lever 64 is pivoted to a bracket 66 connected with a casing 67 communicating by a pipe 68, with av suitable container (not shown) adapted to be arranged within the producer at the point where the temperature is to be controlled. The casing 67 is provided with a diaphragm 69 to which is connected a link 70 having a lost motion connection as at 71 with the lever 64. A sleeve 7 2 is arranged onthe lever 55 on each side of the valve 54, the sleeves being retained in adjusted position by set screws 73, and being pivotally connected by links 7 4 with sleeves 75 on'the stems 76, of valves 78, and 79 arranged within the branches 52, and 53 respectively, the sleeves being secured in adjusted position by set screws 80.

When the temperature in the producer attains a certain height the diaphragm will be movediupwardly a sufficient distance to take up the lost motion between the link 70 and the lever 64, which will rock the lever 55 to open the valve 54. This rocking movement 7 of: the lever 55 willalso open the valves 78,

79. By adjusting the sleeves 63 and 59 on the levers 64 and 55, respectively, the extent of movement of the diaphragm required to operate the valve 54 may be adjusted Within assisted by contracting or extending the link connecting the sleeves 63, and 59.

in operation the suction of the producer through the casing 22 will open the air inlet valve 24 a distance depending upon the strength of the draft and also upon the position of the weight 27. The swinging movement of the lever 2, will swing the yoke 48, and through the connection of the yoke with the valves 40 in the branches 38 and 39, such valves will also be opened to admit a proportionate quantity of inert gas and steam, the connections between the valves and the yoke being adjusted to properly proportion the quantities of each admitted. The rocking of the lever 2 will tilt the water cup, so that a definite quantity of water will pass through the spout into the tunnel 32 and from thence into the casing 22, it being understood that a continuous supply of water is being delivered to the water cup in any suitable manner, the overflow pipe being adjusted therein to retain the level of the water constant in the said water cup.

Until the temperature in the producer has attained a predetermined height, the thermo stat will exercise no action on the regulator. lVhen, however, .this height is attained, the thermostat control will come into action, opening the valve 54 and the valves 78 and 79 to admit a predetermined amount of inert gas and steam to combine with the air admitted by the valve 24. The amountof and steam admitted by the valves 54, 78 and 79, will depend upon the temperature in the producer, the object'being to maintain the temperature approximately constant at a predetermined point. hen the thermostat control comes into operation, it co'riperates with the mechanism shown at the left of Fig. l, and before suca control comes into operation the mechanism shown at the left of Fig. 1 will regulate the proper mixture of the gas and water or steam to the producer. It is necessary to have such a double control for close regulation of the condition of the fire in the producer asit is obvious that proportioning the quantity of water, steam or inert gas to the quantity of air taken in will not be correct and will not maintain the same conditions in the producer nor produce an unvarying quality of when the moisture content and composition of the fuel varies thereby effecting the temperature oi": the fire all of which however, is avoided by using this thermostatic control as an adjunct to the quantity proport-ioning apparatus which latter, however, is necessary to regulate con ditions by proportioning the mixture when starting up inorder to produce an approximately proper gas soon as possible and before the heat of the fire has reached the thermostat bulb in the tire. This is. necessary as no thermostat bulbs have yet been devised which can be placed in the decomposition zone on account of the great heat and it is only possible to insert them in such a part of the producer which does not become so greatly heated but which will be maintained at a proportionate temperature as the zone whose temperature is to be controlled.

It will be understood, that the amount of steam and inert gas, and of water admitted is regulated in accordance with the amount of air admitted, and this is true whether the admission of the diil erent substances is controlled by the thermostatic control or by the strength of the draft. hen the draft through the producer is increased the amount of air admitted is necessarily greater, and the temperature would rise accordingly, but since there is a greater admixture of steam and inert gas admitted, the combustion is controlled and the temperature held constant. The thermostatic control supplements the action of the balanced lever control. lVith the latter, the ratio of the mixture of steam and inert gas to the air is constant after adjustment, while the former varies the ratio of the mixture to the air in accordance with the temperature in the producer. When the thermostat admits more or less mixture of steam and inert gas it naturally decreases the draft through valve 24 and automatically admits less air. The same holds true of the relation between the admission of mixture by valves 40 and draft through valve 24.
